Can organic fertilizers replace chemical fertilizers? – Case Study of Olive from Quetta

Olive is an important cultivation for Pakistan – it is not just regarded as a fruit with positive health benefits, but is also of religious importance to Pakistanis. Moreover, olive has immense potential to be exported. This article will see whether organic fertilizers offer a better alternative to chemical fertilizers in our goal for sustainable agriculture.

A study was conducted in an open field area at the Balochistan Agriculture Research & Development Center, Quetta using both, mineral and organic fertilizers.

To better display the results, we will employ the use of graphs to explain the effect of each fertilizer on plant height, number of branches per plant, and stem diameter.

The results shown in the above graphs exhibit that using just inorganic fertilizers may not be as useful as the inter-mix of both organic and inorganic fertilizers. It is important to notice that balance of fertilizers can result in a nutritious and healthy olive crop, specially for olive sampling that is one year old like in this case study. Trees are quick to absorb the nutrient content this way and there is also possibility of soil fertility enhancement in this way.
